The adsorption of the surfactants mixtures of different chemical l nature such as Triton
X-100 and sodium hexadecyl sulfate at the surface of graphitized carbon black was
studied. Using the model of phase separation (the Rubi–Rosen approach), the composition
of the mixed adsorption layers and parameters of interaction between the surfactant
molecules in the adsorption layers were calculated. It was found that mixed adsorption
layers are enriched with molecules of the non-ionic surfactant Triton X-100.

INTRODUCTION. Adsorption of sur-
factants (SAS) at the phase boundary solution –
solid is the subject of many studies, but most of
the work in this area is devoted to the study of
adsorption from single-component solutions [1–
4]. The study of the behavior of mixed systems
of surfactant is relevant from both scientific and
applicative points of view. In many cases, the
use of mixtures is more advantageous than the
use of separate surfactants [5,6]. The use of
mixtures of surfactants allows regulating of the
disperse systems properties more effectively
compared with the individual components that
are part of the mixture. This is due to the change
in the properties of the components in the
mixture, for example, by increasing or decreas-
ing adsorption at the interface of the phases.
Thus, the wetting and modifying effect of so-
lutions of binary mixtures on solids of different
nature is significantly different from the effect
of solutions of individual surfactants [7]. At the
same time, there is a very limited number of
studies related to the adsorption of surfactant
mixtures, and these works were performed
mainly on hydrophilic surfaces [8–10]. The
analysis of literature data shows that there is
virtually no data on the adsorption of surfactant
adsorption on carbonaceous sorbents, which are
often used in practice, in particular in water
treatment.
The purpose of the work was to study the
adsorption of binary mixtures of surfactants of
various chemical nature on the surface of non-
porous hydrophobic carbon sorbent at different
SAS ratio in mixtures.
EXPERIMENT AND DISCUSSION.
Surfactants of anionic and neonic type were
used for studies. Non-ionic surfactant –
oxyethylated octylphenol with the degree of
oxyethylation n=9-10 Triton X-100 (ТХ-100) of
the general formula С8Н17С6Н4(ОСН2СН2)n,
qualification "p.a.". Anionic surfactant – sodium
hexadecyl sulfate (n-C16H25SO4Na), quailfica-
tion "p.a.". Substances were used without
additional purification.
As a non-porous carbon sorbent, gra-
phitized carbon black was used, the specific
surface area of which, calculated by adsorption
of argon by the BET method, was 105 m2/g.
Determination of the critical concen-
tration of micelle formation (CCM) in the
solutions of surfactant was carried out using a

tenenziometric method based on the dependence
of the surface tension (σ) on the equilibrium
concentration of surfactant (C). The CCM of the
surfactant is defined as the concentration
corresponding to the point of the break in the
dependence σ(lnС).
Measurement of the surface tension was
carried out by Wilhelm's method by balancing
the platinum plate. The cleanliness of the plate
was controlled by the surface tension of the
bidistilled water (σ=72.5 mJ/m2). The accuracy
of measurements at the results of 3–5 points was
± 0.5 mJ/m2.
To obtain adsorption isotherms of
solutions containing different initial concen-
trations of surfactants, they were shaken with
constant sorbent sample weights on a special
apparatus, which carries 6000 oscillations per
hour. The volume of the solution was 0.025 dm3.
After reaching the adsorption equilibrium, the
solution and sorbents were separated by
centrifugation. The equilibrium concentrations
of ТХ-100 were determined by spectro-
photometric method, sodium hexadecyl sulfate -
by the two-phase titration method [11].
Measurement error did not exceed 1% and 4%
respectively. Investigations of the adsorption
kinetics have shown that the adsorption
equilibrium in the aqueous solution of surfactant
- sorbent is reached in 8 hours.
The value of specific adsorption was
calculated by the ratio
V
m
CCa eo −= , (1)
where а is the adsorption value, mol/g; V –
volume of solution, dm3; m – weight of sorbent,
g; Co and Ce– initial and equilibrium
concentrations of the surfactant solution,
mol/dm3.
Fig. 1 shows adsorption isotherms for
solutions of individual surfactants and their
mixtures with different molar ratios of com-
ponents in the initial solution. The molar
fraction of non-ionic surfactant TX-100 in the
mixture (αтх-100) was 0.2, 0.4, 0.6 and 0.8.

Fig. 1 shows adsorption isotherms for solutions
of individual surfactants and their mixtures with
different molar ratios of components in the
initial solution. The molar fraction of non- ionic
surfactant TX-100 in the mixture (αтх-100) was
0.2, 0.4, 0.6 and 0.8.
The adsorption isotherms of ТХ-100 and
SHDS on the surface of the GC have a
Langmuir form. As can be seen from Fig. 1,
with a small content of ТХ-100 in the mixture
(αТХ-100 = 0,2), the adsorption from binary
solutions on the surface of the GC is small (0.35
mol/kg). With the growth of αТХ-100, the
adsorption increases, probably due to the
formation of mixed aggregates ТХ-100-SHDS.
The greatest increase in adsorption of surfactant
is observed at αТХ–100 = 0.8, when its value
reaches 0.56 mol/kg. Previous studies have
shown that the adsorption of surfactant on a
hydrophobic surface occurs due to the
nonspecific dispersion interaction between
hydrocarbon radicals of surfactant molecules
and the nonpolar surface of graphitized carbon
[6].
For comparison with the experimental
data, the values of the total surfactants ad-
sorption on the GC were calculated with the
assumption of additivity:
Acalc=αTХ-100·ATХ-100+(1–αTХ-100)·ASHDS, (2)

ISSN 0041-6045. УКР . ХІМ . ЖУРН ., 2019, т . 85, No5 71
where αTХ-100 is the molar fraction of ТХ-100 in
the mixture, ATХ-100 and ASHDS - adsorption
values ТХ-100 and SHDS from individual
solutions on GC.
Table 1 shows the experimental values of
the total adsorption of surfactants on the GC and
calculated by the formula (2). The results show
that for all molar ratios of components in the
mixture, except for αТХ-100 = 0.2, the values of
total adsorption in systems ТХ-100-SHDS,
obtained experimentally, are greater than the
calculated values (Aexp> Аcalc).
Thus, in mixed systems of surfactant
with a high content of ТХ-100 (αТХ-100 = 0.4, 0.6
and 0.8) there is a synergistic effect, which
manifests itself in increasing of the surfactant
adsorption from the mixture in comparison with
surfactant adsorption from individual solutions.
The maximum deviation from the ideal was
found in the binary solution of surfactants with
the highest content of ТХ-100, when αТХ-100 =
0.8. Probably, in this case, surfactants are
adsorbed on the GC both in the form of
molecules and ions, and in the form of mixed
aggregates.

Experimentally from the data of
adsorption isotherms, the concentrations that are
necessary to achieve maximum adsorption of
surfactants on the surface of the GC were found.
The theoretical value of these values for the
ideal state of the system was calculated by the
formula [5,12]:
1/ С12 = αTХ-100 / СTХ-100 + (1-αTХ-100) / СSHDS, (3)
where СTХ-100, СSHDS і С12 – concentrations
necessary to obtain maximum adsorption on the
surface of the GC, determined by the adsorption
isotherms of surfactants from individual and
binary solutions, respectively; αTХ-100 - molar
fraction of ТХ-100 in volume of solution.
Fig. 2 Dependencies of concentration required to
obtain maximum adsorption on the GC surface in the
individual and mixed SAS solutions, on the molar
fraction of ТХ-100 (α); calculated and experimental
data.
From Fig. 2 it is evident that
experimentally determined concentra-tions
required to achieve maximum adsorption of
surfactants from mixtures on the surface of the
GC (С12) are lower than those calculated for the
ideal state of the system. The most negative
deviation of these values is observed with αTХ-100
= 0,8. These data confirm the synergistic effect
of ТХ-100 and SHDS mixtures during ad-
sorption on GC. In order to calculate the
composition of mixed adsorption layers of
surfactant and parameters of intermolecular
interaction, a phase separation model (Rubin-
Rosen approach) was used [5, 12]. According to
this model, the coefficient of intermolecular
interaction in the adsorption layer βs was
estimated by the formula:

Thus, having determined experimentally
the concentrations of the mixture and individual
surfactants, at which a given adsorption value is
reached, the composition of the mixed
adsorption layer was calculated for a given
adsorption value.

The results of calculations show (Table 2)
that the composition of the adsorption layer on
the surface of the GC is significantly different
from the ratio of surfactants in the solution. The
value of the parameter χ indicates that the mixed
adsorption layer on the surface of the GC is
enriched with non- ionic surfactant molecules,
even with a small its content in the solution
(αTХ-100 = 0,2). With an increase in the ТХ-100
molar fraction in the binary solution from 0,2 to
0,8 its share in the adsorption layer increases in
approximately 1.5 times. Negative values of the
interaction parameters βs indicate excessive
attraction of the molecules and ions of the
mixture components in the mixed adsorption
layers. An increase in the absolute value of the
parameter βs with an increase in αTХ-100 in the
solution characterizes the enhancement of the
interactions between the components in the
adsorption layer.
CONCLUSIONS. Thus, in the course of
experiments carried out for mixed systems of
SHDS-ТХ-100, the existence of a synergistic
effect in relation to an increase in the adsorption
of surfactants on the GC surface was
established. It is found that mixed adsorption
layers are enriched with molecules of the non-
ionic surface active substance of the triton
X-100.

The purpose of the work was to study the adsorption of binary mixtures of surfactants of various chemical nature on the surface of non-porous hydrophobic carbon sorbent at different SAS ratio in mixtures. The results of calculations show that the composition of the adsorption layer on the surface of the GC is significantly different from the ratio of surfactants in the solution. The value of the parameter χ indicates that the mixed adsorption layer on the surface of the GC is enriched with non-ionic surfactant molecules, even with a small its content in the solution (αTХ-100 = 0,2). With an increase in the ТХ-100 molar fraction in the binary solution from 0,2 to 0,8 its share in the adsorption layer increases in approximately 1.5 times. Negative values of the interaction parameters βs indicate excessive attraction of the molecules and ions of the mixture components in the mixed adsorption layers. An increase in the absolute value of the parameter βs with an increase in αTХ-100 in the solution characterizes the enhancement of the interactions between the components in the adsorption layer. Thus, in the course of experiments carried out for mixed systems of SHDS-ТХ-100, the existence of a synergistic effect in relation to an increase in the adsorption of surfactants on the GC surface was established. It is found that mixed adsorption layers are enriched with molecules of the non-ionic surface  active  substance  of  the  triton  X-100. The adsorption of the surfactants mixtures of different chemical nature such as Triton X-100 and sodium hexadecyl sulfate at the surface of graphitized carbon black was studied.
